/A/ VE/V 70@ JOHN WEST, or soUfrHPoR'r, ENGLAND.'

' To all whom it maycnccrn: i

Be' it known that I, JOHN `WEST, a subject lof the King of GreatBritain and Ire- Iland,`resi`ding at The Fir-s, Park Road,

:f Southport, England, have invented certain new and useful' Improvements in Dischargf ing fand Charging Machines for Gas-Rev I *,torts, of'which the folloiv'ing is a specificaation'.

'e' lVIyinvention for. an improved discharg- ,ig' and charging machine Vforges retorts "'f'has for its object to discharge the coke from i' thegas retorts by pushing thecoke through the' retort vby means of a ram constructedv in the form of ascoop and 4operatedby a' v A, l

wvhole'of the coaldePQStd Within ,retort chain, Wherebylthe coke is discharged from the retort, and the'coal fed int-o the retort at the same-time, the coal being deposited :fand left in theretort when the"scoop is 2O` Withdrawn from theretort. In order to accbmplish'this' object I construct a telescopicr ram .1n the form of tivo or more scoops, the* first or` outer scoop being provided with a hinged plate which, when the.

scoop enters the .ret-ort, comes into direct This scoop is provided with atb'ar extending throughout its length and fixed to the bottom of the scoop and projecting b'eyondthe scoop bottom toV form a stop for the hinged plate.

l The ,second or inner scoop is provided "'Witl'i'a channel path for the chain operating theloutward and backward :stroke of the scoops. One end of the chain is attached to the end of the bar in connection with the first or outer scoop -and'traverses when in :operation the channel path of the second or inner scoop; the object of the channel path Vbeir'igto' form a casing in' which the links forming the chain arel kept rigid when it j"is 'pushed forward in the act of causing the -'scoops to enter Jthe retort; the chain on the 'return' stroke being kept rigid by being in A ,tei'ision. ".structed'on' the rarnework of the machine,

A similar channel pat-h is conthis4 pat-li: being of sufficient length. to accommodate the tota-i length of chain required tov complete the operation.

Fig. 7 is an end elevation of' the mechanism shown lin Fig. 6.v Figs. 8, 9, l0, l1 and 12 are diagrammatic figures showing the'action of the discharging and charging apparatus when discharging and charging a retort.

Referring to the drawings the frame a of the .discharging and charging machine is mounted on Wheels b which travel :along rails in front of tlie'retort bench. The discharging and charging apparatus'with the clutches so that "either the hoisting or-tra-v telescopic scoop e suspended by a hanging frame d .is hoisted or lowered by the chainsref in- 'ccni'ection vwith the hoisting and 'traveling gear f which is provided with eling gear maybe put in and out of gear as may be required.

As shown in Figs 3, et and .5, the com..

.billed discharging 'andf charging ,apparatus consists of a telescopic'ram and 'scoops of which g is the' outer scoop and g1 the innerA scoop, h .the hinged plate or. ram hea-d; the

lbarextends throughout the length of the outer scoop g and is lixed along the bottom and-projects beyond same to form a stop for the hinged platez.,

The channel. path k vfor the chain Z is secured to that portion of the second or in? ner scoop g1 which projects beyond the scoop g when the two. telescope, thescoop g1 being longer than the scoop g.' The end ofthe' chain Z-is attached tothe end of the bar -i in connection; with the first or outer scoop g.

and traverses, when iii-operation, the channel path 7c of the second or inner scoop g1, the channel path k forming the-casingin which the links forming the chain Z-are kept rigid when pushed forward in theact of causing the scoops -to enter the retort.

AJsimilar channel path z'l (see Figs. 4, 5. yand 6) `is constructed on the framework of the machine and carried around to form a path sufficiently long to accommodate the to- I tal length of chain to-complete the operation. m (see Figs. 4 and 5) is the stop plate with bar m1 which travels forward with the second scoop g1 and is held stationary at the .end of its forward stroke by the 1- pawls m2 whichengage with the fixed stops m3 (Fig. 2) on the hanging frame d.

The bar m1 may be constructed of two parallel bars as shown on the ligures and is provided with a cross-head n which travels along a path nl (see Figs. 4 and 5). The

bar m1 to `which the-stop plate 'm is attached is vcarried forward to its position .in the retort by the forward movement of the inner scoop g1 which vis fitted with stops 77- (See I Figs. et and 5) which engage with'the stop plate m, andthe continued movement of t-lic scoop drags the stop plate m and its bars -ml with fha orosshead attached to'it until back into the machine on the return stroke ofthe scoops gand g1 afterthey have telescoped themselves into each other, and upon the complete charge of coal being deposited in the retorts; the pawls m2 are lifted out of the lstops mi by meansof a projecting piece g (Figs. 4 and 5) liked to -the inside of the inner scoop g1 which projecting piece 'g strikes -th'e lever4 1 'fixed .to the shaft to whichthe pawls #Rare secured.- The stops p immediately afterward come in contact.

with 'the fixed stops or projecting piecesgl formed on J the bar m1 and the continued 'backward movement of the scoops brings the stop plate m and its bar back into the fram of the machine.

In ordertoprevent-the inner scoop g1v leaving the machine on the outward stroke ``unti1\l the outer or -lirst' scoop g has untelescoped itself from thednner scoop g1, I pro-l 'vide means for holding the second scoop xq* in the frame of the machine; 4to elect this,

two holes or slots a: (see Figs. 2, 5 and 6) are ma e in the bottom of the scoop g.

These h les engage with' -the catches :v1 fitted to levers :1:2 fixed to a shaft az on the endof which there is a lever which is operated by: a cam :v5 rotated by thefdriving `mechanism for pushing .thescoo' s in and out of, the retort; 'the 4cam :v5 being timed to move the levers and catches :v1 at the proper time to release the inner scoopg.

The figures on the accompanying draw? ings show another set of this catch gear for holding the inner scoop; very similar to the first set and acting to hold the inner scoop g1 while the outer scoop g telescopes into it by preventingv its return'to the machine before its time. This-second set is operated by the cam as? driving the lever m7 which is ios free on the shaft the' shaft serving as a v fulcrum for the leveg (see Fig. 7).

rlhe mechanism fordriving the chain Z which puts the scoops and stop plate into motion consists of a suitable reversing mot'or y (see-Figs. 1 and 2 with a train of gearing for rotating the c ain wheel y1 (see Figs. v2, 4,- 5, and 6) engagingwith the chain Z. The Figs. 8, 9, l0, 11 and 12 are diagrammatic views which illustrate the principal actions of the discharger and charger when operating-on a retort, Fig 48 showing the position of t-he ram discharger and scoop closed uprin the machine and ready to eject the coke from the retort.. Fig. 9 shows `the ramhead Lpnshing the coke forward4 and at the same time the somme am followi'tfr" into the retort after receiving the supply of coal from the hopper r when passing the outlet from this hopper. Fig. 10 shows the retort from which` the coke has been ejected, also the completed forward stroke of theram head la. the loaded scoops g and g1 and the position of the stop plate m which, as before described, is caused by means of pawls to be held in the frame of the machine untiltho scoops have delivered their chargeof'coal to the retort. For'the convenience of illustrating ythe position of the scoops, the stop plate, ram head bai and chain when all are extended to their full stroke, the Fig. l0 has not been drawn with "the coal in the scoops; it being understood that in this position the scoops are loaded with the coal received from the coal hopper c" as they entered the retort.

Fig. 11 shows the scoops returning to the machine and as the coal'cannot pass back owing to it being held by the temporarily fixed stop .plate m the coal leaves the scoops and is deposited on to the floor of the retort,

A and in consequence, after the scoops are withdrawn, the retort will be completely charged with coal. The Fig. 11 also shows the swinging ram head or plate which hinges upward, so as to pass over the coal,

the contact with the coal causing the head to partly rotate around its hinge pin.

The Fig. 12 shows the retort completely charged with coal and the discharger and scoops back into the frame of the machine as also shown in Fig. 8.

A stop is'provided in the channel path c to prevent the scoop g leaving the scoop g1 when fully extended and projectionsv 'or stops are provided on the outsides of the inner scoop g1 against which the outer scoop closes when fully telescoped on the inward stroke, the cont-inued motion of the outer scoop g being thus transmitted to the inner scoop g1.

lhat I claim, and desire to secure by Letters Patent is 1. In a gas retort charging and discharging machine, in combination, a telescopic scoop comprising a plurality' of sections, each of said sections having a channel formediin its bottom and means positioned within said channels for operating said sections.

' 2. In a gas retort charging and discharging machine, in combination, a telescopic scoop comprising a plurality of sections, each of said sect-ions having a channel formed in its bottom and a chain positioned within said channels for operating said sections. l l

3. In a gas retort charging and discharging machine, in combination, a frame, a telescopic scoop comprising a plurality of sections mounted upon said frame, eac of said sections having 'a channel formed-in its bottom and a chain positioned within said channels for operating said sections, said frame being provided with a. pathway adapted to receive said chain and maintain it -in a rigid extended position.

-4. In a gas retort charging and discharging machine, in combination, a telescopic scoop comprising a plurality of sections, a catch normally holding the lnner section in position until the outer section is in its extended position, a lever upon which said catch is carried, driving mechanism for op! carried, driving mechanism for operating said sections and means controlled' Aby said driving mechanismfor actuating said levers to release the catches associated therewith from their holding positions.

l In testimony whereof I have 'afixed my signature, in presence of two witnesses.
